3.5.3 Failures occurring when the Ring Protocol functionality is used
This subsection describes failures occurring in the Autonomous Extensible Ring Protocol.
The Autonomous Extensible Ring Protocol (abbreviated hereafter to Ring Protocol) is a
Layer 2 network redundancy protocol for ring topologies.
If communication is not possible when the Ring Protocol is used, use the following analysis
flowchart to determine the problem and isolate the cause.
Figure 3-1 Analysis flowchart
If operation cannot be performed correctly or a ring network failure is detected when the
Ring Protocol is used, use the failure analysis method described in the table below to
isolate the cause of the problem for the relevant node in the target ring network.
The analysis method described in the table below applies to the AX1250S and AX1240S
series of switches. For other AX switch series, see the manuals for the appropriate models.

No. Items to check and commands Action
1 Use the show axrp operation
command to check the operating
status of the Ring Protocol.
If enable is displayed for Oper State, go to No. 2.
If a hyphen (-) is displayed for Oper State, required items for
using the Ring Protocol have not been configured. Check the
configuration.
If disable is displayed for Oper State, the Ring Protocol is
disabled. Check the configuration.
If Not Operating is displayed for Oper State, the Ring
Protocol functionality is not running. Check the configuration for a
conflict.
2 Use the show axrp operation
command to check the operating
mode.
If the operating mode defined in the network configuration is
displayed for Mode, go to No. 3.
If any other information is displayed, check the configuration.
